DIE FORBUTTONS.

SPECIFICATION forming part of Letters Patent No. 239,357, dated March29, 1881.

Application filed January 28, 1881. (No model.)

To all whom it may concern:

Be it known that I, DOUROO D. VVILLIAM- SON, of New Brunswick, in thecounty of-Middlesex and State of New Jersey, have invented 5 a new anduseful Improvement in Dies for Buttons, of which the following is suchfull, clear, and exact description as will enable others skilled in theart to which this my invention relates to make and use the same whentaken in connection with the accompanying drawings, in which- Figure 1shows a "ertical section through the center of the face-die, ring-die,and male die. Fig. 2 shows same section through female Fig. 3 shows samethrough ring-die and male die. Fig. 4 shows same section throughmodification of male die and ring-die. Fig. 5 shows same section throughanother modification of male die and ring-die. Fig. 6 shows'face of maledie in various outline.

Heretofore and beforethis my invention, dies for buttons, whether suchbuttons were formed of composition, rubber, or horn, or like substances,were made to consist of two partsthat is, a female die and a maledie-between which the button was formed, thejoint between the two diesbeing formed at the edge of the button about its greatest circumference.Pro- 3ojecting pins were provided on one or both dies to partially formor mark the thread-holes. After the button had been removed from thedies it was finished by removing the feather from the edge thereof,which was formed at r, 5 the joint between the two die-pieces, and theholes were subsequently drilled, making frequent handling of the buttonsnecessary in finishing, whereby they became marred or scratched. 40 Thismy invention consists in so forming the male and female die that thejoint between them will be removed slightly inward from the edge of thebutton; in the combination of pro jecting pins in one die extending tothe face of the other and into holes provided therein for them when thedies are closed; in the formation of the joint between the two dies at aprojection on the face of each, so that the projections will form in thebutton a groove in which any feather formed in the joint will becontained; and the various constructions and combinations hereinafterclaimed.

My invention is especially applicable to the forming of buttons fromcomposition, rubber, horn, or like material, but may be advantageouslyused for other purposes.

The female die consists of the face-die A and ring die B. The face-die Acontains the reverse of the form to be given to one face of the buttonout to the greatest diameter, and the ring-(lie B contains the reverseof the form to be given from the greatest diameter at the line of theface-die A around the edge of the button and a portion of the other orback face of the button. The face-die A and ring-die B are shown inposition in Fig. 2. The ring-die has on its face the groove 6 andprojectionf, so as to form in the face formed therebythe back face ofthe buttona groote about it a short distance from the edgethereof.

At or near the center of the die A the pins 0 0 are rigidly fastened,projecting up to and entering the holes (I d in the male die U providedfor that purpose. When the dies are closed together these pins form thethreadholes in the buttons.

The portion of the face-die A and the portion of the ring-die B whichcome together and form thejoint a are accurately ground and tittedtogether, so that the joint a between them will not permit any featherto be there formed.

The male die 0 is made to closely fit within the ring-die B and formwith it the workingjoint I). The face of the male die 0 is here shownhaving a concave or depression, g, at

the center and curving to nearly flat at the edge, inakin g theprojection h aboutit, so that the faces of the male die 0 and thering-die B will, when brought to a closed position, as shown at Fig. 3,have about or at the edge of the joint I) a projection formed off h,through the center of which I) the joint is, so that any feather formedin the joint b will be in the depression in the button formed byprojections f h and below the back face, of the button.

The face of the male die and ring-(lie may be made without theprojections and h, and are so shown in Fig. 4; but buttons made in dieswithout projections f and h are apt to have a feather formed in thejoint 11, projecting beyond the face of the button, which must beremoved to give a good finish, while buttons made in dies having theprojections)" and it have any feather that may be formed in the joint I)at the bottom of the groove made by the projectionsfand h, and whollybelow the back face of the button.

The male die 0 and ring-die B may be made so that the joint I) will beformed in a depression in the dies, as shown at Fig. 5, whereby therewill be made on the button formed therein a projection or head, on whichany feather formed in the joint I) would be, and from which it could beremoved with little labor or danger of mar-ring the button.

The face of the male die may have a circular boundary, or star-shaped,octagonal, or other form, as shown in Fig. 6, the inside of the ringdieB, which forms with the male die the joint I), being made ofcorresponding shape.

The dies may be cut to make round, oval, octagonal, spherical, or otherforms of button having the same peculiarities as those described hereinwithout departing from my in- Vention.

The male dieand ring-die are each cut away so as to form the groove orannular space It between them, into which the waste stock will be forcedthrough the working'joint b by the operation of the dies.

The operation of the dies is asfollows: When forming buttons ofcomposition which is nearly liquid, plastic or powdered, the die A andringdie B are securely fastened together so as to form the female die,into which a sufficient amount of the composition is deposited, and themale die is forced down upon it, pressing the composition tightly in thedie, any surplus or waste stock being forced into the groove 70. Themale die 0 and ring-die B are then sepa' rated from the face-die A andthe button re moved. The button so made is found to be finely finishedand provided with thread-holes, ready for the market without. furthertinishin g, unless a male die and ring-die without projections f and hare used, when it may be necessary to remove a feather formed in thejoint I) from the button.

When rubber, horn, or a composition ofmore firm and solid consistency isused to form buttons from, it is usually cut or formed in blanks ofproper size to be fed to the dies. The blanks may be inserted beforebringing the ring-die B and face-die A together, or they may be formedof such diameter as'will pass through the ringdie when it is in positionon the die A, and of such a thickness that'it Will contain stocksufficient to fill the die when the male die 0 is brought into itsclosed position. Buttons so formed are to be removed as above described.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the male and female dies, the working-jointbetween which is removed slightly within from the greatest diameter ofthe female die, substantially as specified and set forth.

2. The combination of a face-die, and a ringdie for forming the edge anda portion of the reverse face near the edge with a male die titting theinner edge of the ring-die, substantially as specified and set forth.

3. The femaledie, formed by the colnbinatio of the face-die and ring-dieprojecting over the face-die, substantially as specified.

4. The ring-die provided on its face, at or near the'edge thereof, withthe projection f, in combination with the male die provided on its facewith the projection h, at or near the edge thereof, so that theprojections f and h form substantially one projection when the dies areclosed, substantially as specified.

5. The combination, with the male die and ring-die, of the annulargroove or space It between the body of the male die and thehody of thering-die, of less diameter than the diameter of the female die adjoiningthe working-joint between the two dies, substantially as specified andset forth.

6. The combination of the face-die provided with pins 0 c, rigidlyattached thereto, and a ring-die for forming the edge and a portion of Ithe reverse face near the edge, with a male die fitting the inner edgeof the ring-die and provided with perforations d d to receive the pins 0c, substantially as specified and set forth.
